Investment Objective/Strategy -The First Trust Total US Market AlphaDEX® ETF is an exchange-traded index fund. The objective of the Fund is to seek investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of an equity index called the NASDAQ AlphaDEX® Total US Market Index.

There can be no assurance that the Fund's investment objectives will be achieved.

The NASDAQ AlphaDEX® Total US Market Index is an "enhanced" index created and administered by The NASDAQ OMX Group,
Inc. ("NASDAQ") which employs the AlphaDEX® stock selection methodology to select stocks that meet certain criteria from
three indices - the NASDAQ US Large Cap Index, the NASDAQ US Mid Cap Index and the NASDAQ US Small Cap Index.

NASDAQ constructs the NASDAQ AlphaDEX® Total US Market Index by ranking the eligible stocks within the three indices on
growth factors including 3-, 6- and 12- month price appreciation, sales to price and one year sales growth, and separately on
value factors including book value to price, cash flow to price and return on assets. All stocks are ranked within each size class
(Large, Mid, or Small) on the sum of ranks for the growth factors and, separately, all stocks are ranked on the sum of ranks for the
value factors. A stock must have data for all growth and/or value factors to receive a rank for that style.

NASDAQ classifies each stock as either a value stock or a growth stock and each stock receives its style rank from the previous
step as its selection score.

The top 200 stocks from the NASDAQ US Large Cap Index (50% of the total portfolio), the top 400 stocks from the NASDAQ US
Mid Cap Index (30% of the total portfolio) and the top 600 stocks from the NASDAQ US Small Cap Index (20% of the total
portfolio) based on the selection score determined in the previous step comprise the "selected stocks".

The selected stocks are divided into quintiles within their size class based on their rankings and the top ranked quintiles receive a
higher weight within each sub-portfolio (Large, Mid, and Small). Within each sub-portfolio, stocks are equally weighted within
each quintile.

The index is reconstituted and rebalanced quarterly.

Following the close of trading on January 9, 2015, the fund's underlying index changed from the Value Line® Equity Allocation Index to the NASDAQ AlphaDEX® Total US Market Index.

would have generated.

After Tax Held returns represent return after taxes on distributions. Assumes shares have not been sold.
After Tax Sold returns represent the return after taxes on distributions and the sale of fund shares. Returns
do not represent the returns you would receive if you traded shares at other times. Market Price returns
are based on the midpoint of the bid/ask spread. Returns are average annualized total returns, except
those for periods of less than one year, which are cumulative. The fund's performance reflects fee waivers
and expense reimbursements, absent which performance would have been lower.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and
do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor’s tax
situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold
their fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

Footnotes

1

The NAV represents the fund's net assets (assets less liabilities) divided by the fund's shares outstanding.

2

Fund shares are purchased and sold on an exchange at their share price rather than net asset value (NAV), which may cause the shares to trade at a price greater than NAV (premium) or less than NAV (discount).

3

Most recent distribution paid or declared through today's date. Subject to change in the future. There is no guarantee that the fund will declare dividends.

4

30-day SEC yield is calculated by dividing the net investment income per share earned during the most recent 30-day period by the maximum offering price per share on the last day of the period.

5

12-Month Distribution Rate is calculated by dividing the sum of the fund's trailing 12-month ordinary distributions paid or declared by the NAV price. Distribution rates may vary.

Market prices may differ to some degree from the net asset value of the shares. Investors who sell fund shares may receive less than the share's net
asset value. Shares may be sold throughout the day on the exchange through any brokerage account. However, unlike mutual funds, shares may only be
redeemed directly from the fund by authorized participants, in very large creation/redemption units.

Risk Considerations

There can be no assurance that the fund's investment objective will be achieved.

The fund may invest in securities issued by companies concentrated in a particular industry. The fund may invest in small capitalization and mid capitalization companies. Such companies may experience greater price volatility than larger, more established companies.
